OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 394,424, dated December 11, 1888.

Application tiled April 4, 1888. Serial No. 269,548. (No model.)

T @ZZ whom it may concern:

Be it known that I, WILLIAM II. WILKIN- SON, of Boston, in the county of Suffolk and State ot lvlassachusetts, have invented a cer-v y Fig. 3 is another view ot my device also detached from the oil-cup.

In the drawings like letters ot' reference indicate corresponding parts.

A, Fig. l, represents the body of the oil-cup, which is usually made of glass, in order that the operation of the feeding device and iow of the oil may be better observed.

B is the top of the oil-cup, which is preferably made oi' metal and formed to set over the top of the body A, and atthe same time to be adapted to be raised from the body, in order to replenish the cup with oil by sliding the said top upward upon the tube C. i

C is a .fixed vertical tube secured to the bottom or base D, extending' upward through the center of the body of the oil-cup A and through the top or cover B. Near the bottom of the tube C, and within the body of the oilcup, are made one or more small holes or oritices, (represented by 1,) through which the oil from the cup passes into the interior of said tube, flowing thence downward through the valve nv into the receiver or drip h, which in turn conveys the oil or lubricator to the jonrnal or Inachinery to be lubricated.

In the lower part of the base D are placed one or more holes, g, extending inwardly or through said base, for the purpose of permitting an observation of the quantity of oil flowing downward and out of the drip-tube 71.

Vithin the tube C is placed a rod, f,.the bottom of which is suitably formed to make the valve n.. The valve-rod f is suitably secured to the top and thunIb-piece o, by which means the valve yn is operated. The top and thumb-piece are suitably threaded in the inside ot the top of the tube C, so that when the thumb-piece oA is turned it of course raises or depresses the valve-rod f and opens or closes the valve n, according as the thumb-piece u is turned eitherto the right or let't. Near the top of the tube C, I place the lixed collar d. This collar may be made integral with thc tube C, if desired. lIpon the upper surface of the annular collar d are formed notches s. Above the fixed collar d., already described, is placed the loose or movable collar c. U pon the under side of the surface of the annular collar c are formed notches .5', the said notches e' corresponding with thc opposite and contiguous notches, e', :formed in the tixed collar (l, as before stated.

III the loose collar c is formed the notch fr, into which the spring-catch y is adapted to engage. The spring-catch yy at its upper end is secured to the under side of the thumbpiece a., as shown. A spring, l), is preferably placed over the loose collar c to aid in holding i-t in position, the upper end of the spring being secured to the under side of the thumbpiece a, while the other end ot' said spring rests upon and presses downward upon the upper surface of the loose collar c. The spring l) and the spring-catch y are pretcrabl y made circular in form, as shown, butmaybe ot' any convenient form or kind.

The special object oit my present invention is to secure a simple, positive, and correct gage by which to measure and regulate the fiow ot' the oil through the valve `n..

I am aware that various devices have been employed upon oil-cups olf the usual construction to effect this purpose; but all, so far as my knowledge extends, are liable to become inoperative in use, and in none of' the devices heretofore employed is 'found that correctness, simplicity, and delicate adjustability so desirable in a device ol this kind.

Having now described the several parts of my invention, I will explain the mode ot' its operation, which is as tollows: The springcatch y is inserted in the notch or detent o3, formed in the loose collar c. The said collar is then raised suliiciently, so that the notches ,e and e are disengaged, and then the thumbpiece o, with the loose collar c, is turned one ormore notches. The turning out ot the thnnIb-piece o., ot. course, will open the valve n, corresponding to the distance it is turned, and of course also corresponding to the number of notches lthat the notches .e are turned IOO 1 pass the valve n, and from thence to the machinery. Then it is necessary to close the valve-as, for instance, when the machinery stops-all that is necessary is to raise the sprin g-catch `y out of the detent and turn the thumb-piece a in the direction necessary7 to close the valve In. Now,when it is again desired to permit the iiow of the oil, the quantity having been already gaged by the relative position of the loose collar c as adjusted upon the lfixed collar d in the notches .e and e', by simply turning` the thumb-piece a backward, so that the spring-catch g/ will again engage the detent @70, the valve n will be openedY the required distance, as before. By this means it will be seen that it is always possible, after having adjusted the valve so that the desired ilow of oil is obtained, to close the valve and to open it exactly the same distance each` time. It will also be observed that the engagement of the notches ,e and e" forms a positive adjustment or gage, the ineness of the notches regulating the iineness of the adjustment. Another advantage of this device is that the jar of the machinery can never disengage the notches, and so permit the valve to be opened or closed by the turning of the thumb piece either one way or the other, which, in all devices not of a positive character, is liable to occur. My device also has no screw-heads or other projecting parts which are liable to be knocked 01T. Neither is there any portion of the device which can become loose and inoperative by any ordinary use or any extraordinary jar which may come to the special machinery to which the oil-cup is attached.

Having now fully described my invention,

what I claim, and desire to secure by Letters ranged and adapted to operate substantially as and for the purposes described.

2. In an oil-cup, the tube C, provided with the iixed collar cl, having the notches z', in combination with the loose collar c, provided with the notches ,e and adapted to gage the iow of oil in the delivery, substantially as and for the purposes described.

3. In an oil-cup, the thumb-piece a, suitably secured to a valve-rod, the spring-catch y, and loose collar c, having notches z, in combination with a tube, C, provided with the liXed collar d, provided with notches z', all substantially as and for the purposes set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 27th day of March, A. D. 1888.
